A2 fsi manifold flap operation

Ok so symptoms are at full throttle around 4K car is choked ie wont rev fast its like hitting the limiter. If I pump the accel. It will sometimes clear and you can feel the power come back but doesn’t last.
1. What is causing this ? I cleaned out the air intake with sea foam carb spray. It started after that well the lack of power always been there.
1. Changed plugs no difference
2. Just added Forte injector cleaner to the fuel tank to clean injectors.
3. I wonder if the sea foam has dislodged something and its blocking the air? Suspect EGR Valve. If this isn’t working right will it cause this symptoms?
Thanks guys.
